• one of the oldest developed measures of basic activities of daily living
  • originally developed to assess the severity of disability in personal care and mobility in stroke patients.
  • consists of 10 items:
    1) Bathing
    2) Grooming
    3) Feeding
    4) Dressing
    5) Toilet use
    6) Ascend/descend stairs
    7) Bowel management
    8) Bladder management
    9) Bed/wheelchair transfer
    10) Mobility (level surface)

Clinical Considerations

  • The BI is one of the best-researched ADL tools and has been used with a number of patient populations. Use of adaptive aids is permitted with a score of ‘independent’.
  • The BI covers very basic functional abilities and while a score of 100 suggests independence, assistance may still be required with other higher order tasks such as cooking/cleaning and therefore other measures are needed to assess these areas.
  • Though the test items are deemed important to society, they may not reflect activities that are of importance to individuals with SCI.
  • There is minimum patient burden unless the entire test is scored by observation. Floor and ceiling effects makes the scale less useful for the SCI population.

Activity ▶ Self-Care

Administration

  • Scores are obtained primarily from using direct observation
  • Self-report, or proxy responses (from family/friends) have been reported.
  • Scores based on performance in the past 48 hours are preferred.
  • Administration takes:
    • 20-30 minutes to complete by direct observation
    • 2-10 minutes to complete for self-report or proxy

In the original version, each item is scored in three steps. **A modified Barthel Index (MBI) with a five-step scoring system, developed by Shah et al. was found to achieve a greater sensitivity and improved reliability compared with the original version. It has been tested in the SCI population by Kucukdevici et al. 2000 – measurement properties are described below.

Number of Items

10

Equipment

None

Scoring

Item scores are summed to give a total score ranging from 0 to 100 (0: fully dependent; 100: fully independent).

Languages

The 10 item English version has been assessed for the SCI population.

Training Required

No formal training required. However, clinical experience/practice is beneficial.

Interpretability

  • Higher scores indicate a higher level of independence
  • Scores reflect the nursing burden and social acceptability of the activity.
  • Cut scores have been established for the stroke population and are not necessarily representative for the SCI population. Scores of 0-20 indicate total dependence; 21-60: severe dependence; 61-90: moderate dependence and 91-99: slight dependence.
  • Published data for the SCI population is available for comparison (see the Interpretability section of the Research Summary sheet).

MCID: not established for the SCI population, but for a stroke sample (n = 43; mean (SD) age = 55.4 (14.6) yrs; Taiwanese adults post-stroke mean (SD) of 7.04 (64.1) days):

BI MCID = 1.85 points

(Hsieh et al. 2007: “Establishing the minimal clinically important difference of the Barthel Index in stroke patients” Neurorehabil Neural Repair 21(3): 233-238)

SEM: not established for the SCI population, but for a stroke sample (n = 56, Taiwanese adults post-stroke mean of 1197.1 days):

BI SEM=1.45 points

(Hsieh et al. 2007. “Establishing the minimal clinically important difference of the Barthel Index in stroke patients” Neurorehabil Neural Repair 21(3): 233-238)

MDC: not established for the SCI population, but for a stroke sample (n=56, Taiwanese adults post-stroke mean of 1197.1 days):

BI MDC = 4.02 points

(Hsieh et al. 2007. “Establishing the minimal clinically important difference of the Barthel Index in stroke patients” Neurorehabil Neural Repair 21(3): 233-238)

Reliability

No values were reported for the reliability of the Barthel Index for the SCI population.

Validity

Correlation of the Barthel Index is Moderate with:

  • the Walking Index for Spinal Cord Injury (Spearman’s ρ = 0.67)
  • the Rivermead Mobility Index (Spearman’s ρ = 0.6)
  • the Spinal Cord Independence Measure (Spearman’s ρ = 0.7)
  • the Functional Independence Measure (Spearman’s ρ = 0.7).

(Morganti et al. 2005, Plantinga et al. 2006)

Responsiveness

Total score effect size (ES) for all participants = 0.98 (items: 0.38 to 1.16)

(O’Connor et al. 2004)

Floor/Ceiling Effect

Ceiling effects were detected at discharge for the Barthel Index score (24.1% of subjects had the highest score).

(O’Connor et al. 2004)

Modified Barthel Index

# of studies reporting psychometric properties: 1

Reliability

  • Internal consistency of the Modified BI is High at admission (Cronbach’s α = 0.88) and discharge (Cronbach’s α = 0.90).
  • Inter-rater reliability for MBI items range from Moderate to High (ICC= 0.50-0.78).
  • Inter-rater reliability for the total MBI scale is Moderate (ICC = 0.77)

(Kucukdeveci et al. 2000)

Validity

  • Correlations between the MBI and ASIA (American Spinal Injury Association) motor scores were Moderate at admission (r = 0.55) and High at discharge (r = 0.76).
  • Correlations were weaker between the MBI and ASIA sensory scores; Moderate at both admission (r = 0.43) and discharge (r = 0.51).

(Kucukdeveci et al. 2000)

Responsiveness

No values were reported for the responsiveness of the Modified Barthel Index for the SCI population.

Floor/Ceiling Effect

No values were reported for the presence of floor/ceiling effects for the Modified Barthel Index for the SCI population.
